Application of Combination Evaluation Method in Evaluation of Green Agriculture Development Level in China

Abstract

The first document of the central government in 2021 proposed to strengthen the supervision of agricultural product quality and food safety, and vigorously develop green food and organic food. Green agriculture is the core of the future development of modern agriculture, which is closely related to food safety, environmental protection and sustainable use of resources, and is the basis for realizing agricultural and rural modernization. In this paper, three objective weighting methods (entropy method, principal component analysis method, factor analysis method) were used to assign the weight of China's green agriculture development level index in 2018, and then combined with the combination evaluation method to calculate the comprehensive score and ranking. On this basis, the 31 provinces and cities in China were divided into four types by cluster analysis: high level of green agriculture development, high level of green agriculture development, medium level of green agriculture development and low level of green agriculture development. According to the study, Heilongjiang, Shandong, Jiangsu, Henan and Anhui were the regions with higher green agriculture development in 2018. On the other hand, the five least developed provinces and cities are Beijing, Ningxia, Hainan, Tianjin and Tibet. The overall situation of green agriculture development in China is unbalanced among regions. Therefore, according to the agricultural economic basis of each province or city, some suggestions are put forward in the hope of improving the agricultural production environment, improving the quality of green agricultural products, realizing the balanced development of green agriculture among regions and speeding up the process of agricultural and rural modernization.
